CARRIAGE-CURTAIN WINDOW.

Application filed. June 21, 1923. Serial No. 646,839.

To all whom it may concern: I Be it known that I,- LAwRnNon C; NEL- soN, a citizen of the United States, residing in the city 'of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Carriage-Curtain Windows, of which the following is a specification, reference being had to the accompanyingdrawings, forming a part thereof.

The purpose of this invention is to provide an improved and simplified'construction for a carriage curtain window, particularly in respect to the frame for mounting the glass in the curtain so as to effectuallyrexclude water from the junctions between the glass and the curtain on the one hand, and the outer frame member on the other hand, and so as to be economical of construction, and easy of installation. It consists in the elements and features of construction shown and described as indicated in the claims.

In the drawings I Figure 1 is an interior elevation of a portion of the carriage curtain containing a 'window constructed according to this invention.

Figure 2 is a detail section at the line, 2-2, on Figure 1, showing a plain glass.

Figure 3 is a section similar to Figure 2, showing a beveled glass.

Figure 4 is a section at-the line 44. on Fig. 1.

Figure 5 is a detail elevation showing the frame dissected at a junction between the I(3nd members and longitudinal side memers. 7 .Figure 6 is a detail section at the line, 6-6, on Figure 1. Figure 7 is a view similar to Figure 2 showing the frame members,.curtain, glass and bushings,as theywould appear without tightening the screws to clamp the frame members together and compress and expand the bushings.

Figure 8 is a section onthe line 8-8 on Figurel.

In the drawings, 1 1813116 carr age curtain; 2 is the glass of the" window; 3 is the outer frame member; 1 is the inner frame member; 5 and 6 are rubber bushings which are lodged in the inner face of the outer frame member, 3, and extend entirely around the WiI dOW. The outer frame member, 3, is shown as a'die casting and is preferablyvso made. It has a rabbet at 3*, on its inner face extending entirely around the window, said rabbet being dimensioned with respect to the glass, 2, in the plane of said glass so that the glass lodged in the rabbet and clamped therein, as hereinafter described, will-be out of touch at its peripheral edge with the metal of the frame and will be held against edgewi'se contact with said'metal frame by the lateralgrip of the gasket, 5, hereinafter more particularly described, which is lodged in the face of the rabbet and compressed tightly there-against by the clamping together of the two frame members, as hereinafter described. The depth of the rabbet in the direction transverse to the plane of the glass is somewhat greater than the thickness of the glass, as

seenin" Figures 2 and 3, for the purpose hereinafter explained. The face of the rabbet toward the glass has a groove, 3", substantially semi-circular in cross-section eX- tending entirely around the window. Just within the outer margin of the frame memher, 3, it has a groove, 3, which like the groove, 3", extends entirely around the window. The inner frame member, 4, is preferably a sheet metal stamping, as shown, formed hollow, that is, concave toward the glass and-curtain, so that it is adapted to clamp the curtain and glass against the outer member by means of its inner and outer margins only, and it is dimensioned transversely relatively to the transverse dimension of the outer frame member,3, so that said marginal areas,-t and 1 stand opposed respectively to the glass. and to the outer frame member a little inward of the inner margin of the-said outer frame memher and directly opposite the outer margin of the same. The curtain, 1, has its window opening dimensioned with respect to the frame so that the marginal area of the curtain around said opening extends across the entire width of the inner frame member which isthe wider of the two frame memhers and therefore across the entire width of the outer frame member, vas seen in Figures 2 and 3 so that bothmarginal areas, 4 and 4, so the inner member engage the curtain fabric for clamping it between said inner and the outer frame member and, at the inner marginal area clamping it against the gla'ss. I The bushings, ,5 and 6 provided for the lodgement in the grooves, 3 3, respectively, are preferably rubber tubes, as seen in Figure 7 and they are dimensioned respectively in cross section as seen in said Figure 7, considerably larger than the cross section of said grooves respectively, so that being lodged in the grooves inthe assembling of the window members on the curtain when the two window members are clamped together, which is effected by screws, 8, distributed at suitable intervals around the frame, the gask ts are compressed transversely of the curtain and glass, as seen in Figures 2 and 3, so that the rubber of the gaskets is caused to protrude into and completely close the crevices between the outer frame member and the glass at the inner margin and between said outer frame member and the curtain at the outer margin, as seen at 3 and 3 respectively on Figures 2 and 3. As may be understood from Figures 2 and 3, the inner frame member has the holes through which the screws, 8, take for clamping together the two frame members, countersunk in the stamping, as shown at 4, said frame member, 4-, being simply concave, elsewhere in cross section, as seen in Figure 8.

The inner frame member, 4, is desirably made in four parts comprising identically formed end members, P, i, and identically formed opposite longitudinal side members, M, the logitudinal side members being joined to the end members, as may be understood from Figures 5 and 6, the ends of the side members, 4?, being shaped in stamping so as to have a terminal, 12, curved transversely with less radius than the terminal, 13, of the end member with which it is to interlock, the two members being riveted together, interlock-ed, is shown in Figure 6, as indicated by the rivets, 15, seen in Figure 1. The purpose of making the frame in a plurality of sections, as described, is to facilitate assembling frames for windows of different lengths, which is done by merely selecting longitudinal members, 4!, of suitable length for the length of window desired.

The end member, 4", of the inner frame, 4, are formed with integrally projecting strap eyes, 16, for engaging the straps, 17, by which the window frame is securely held to the vehicle frame upon which the curtain material is hung or stretched, to relieve the curtain fabric of the strain upon it which would otherwise be caused by the weight of the window if attached directly to and supported solely by the curtain fabric.

It will be understood that the special function of the gaskets, 5 and 6, dimensioned and compressed and expanded as described, is to completely seal the joints between the outer frame member and the curtain fabric and glass against the entrance of moisture,

pinch that fabric tightly against the glass at one side and against the outer frame member at the other side so as to safely exclude moisture even from the inside of the vehicle without danger of cutting the fabric by such pinching.

I claim 1. In a carriage curtain window, in c0m bination with the glass and the curtain fabric, an inner and an outer frame'member between which the curtain fabric and the glass are both clamped, the outer frame member having on the side toward the inner member just within its own outer periphery, a groove extending in said frame member entirely around the same, the inner frame member being concave toward the outer member for obtamlng clai'npmg engagement by means of its marginal edges only, the two frame members being relatively dimensioned so that the outer margin of the inner frame member faces said peripheral groove of the outer member; arubber gasket lodged in said groove outside the curtain fabric, and means for clamping the two frame members together, whereby the outer marginal edges of theinn'er frame member clamps the curtain fabric against said gasket, and; the gasket against the outer member for causing the gasket to be expanded laterally and protrude between the curtain fabric and the peripheral edge of the outer member to exclude moisture from the curtain fabric.

2. In a carriage curtain window, in combination with the curtain fabric and the glass an inner frame member, and an outer frame member between which the curtain fabric and the glass are clamped,the outer frame member having at its inner margin a rabbet to accommodate the glass, and at its 'outer margin an inwardly-facing groove; the inner frame member being transversely hollowed throughout its entire extent around the window for clamping by means of its marginal edges only, the outer frame member having a concave groove in the face of the rabbet, a rubber gasket lodged in said groove and dimensioned relatively to the groove for being expanded laterally beyond the groove under compression in the clamping of the two frame members together, and rubber gasket lodged in the peripheral groove of the outer member dimensioned with respect to said groove for being expanded under compression so as to extend outwardly beyond the groove, the curtain fabric being extended between both frame members across their entire width for lapping at its inner side on both the marginal edges of the inner member, and at its outer side against the last mentioned rubber gasket 10 and the glass, and means for clamping the two frame members together for compressing and laterally expanding the gaskets to cause them to protrude from the grooves between the frame member and the glass and between the frame member and the curtain fabric respectively.

In testimony whereof 'I have hereunto set my hand at Chicago, Illinois, this 15 day of June, 1923. V
